LabelCraft: Barcode Labels

Looks like it should work... says it should download a PDF on Android... says that it HAS downloaded the PDF... but nope! No PDF is downloaded. Searched everywhere on my brand new Fold Ultra, no PDF downloaded. The Settings and Print History options don't even open, I just tap the menu option and it just sits there.

This is a shame bc I thought this would solve my problems. I need to be able to print labels from my phone wirelessly to a Brother printer in my studio.
